The charges stemmed from reports that jail officials assaulted pre-trial detainees — people being held following an arrest but prior to conviction. On several occasions, the jailers slammed detainees’ heads onto the triage counter in the prisoner intake area or otherwise assaulted or planned to assault them, according to court records.

Records said the acts occurred when prisoners were not “resisting or posing a threat to any officer.”

The men then wrote false reports or failed to file reports about the incidents; they took place in 2006, court records said.
